[Q] No mobile network and missing MTP <-> USB mass storage option

hi all, im new here, but i know how to flash things...
so, as the title said, i have 2 question (or should i say, problem);

1. no mobile network - i have tried all i know, restarting phone, remove the simcard then insert back, wipe data/cache but nothing happen
2. missing MTP<->USB mass storage option - yep, i need this since there are problem that require me to copy all file back, example;
when using MTP, my music file only show 200 when my file is 500 actually, thus i need
to use USB mass storage

EDIT : wanna add more question, in Cyanogenmod, under Setting > development there is a n option to rename our device from "android-somerandomnumber" to "our desired name"...the question is is this option only available in CM? im using OmniROM and there is no that option

@cubflyer
thanks for the suggestion, so there's no way to enable it unless using 3rd party eh?

btw, after this problem i've clean flash my phone and its working now, though there are some app that i cant install, i get this message "App not installed"...that app is awaremote 2.3, havent try others...
